Patent number: 9859984Abstract: A transmitter comprises a complex mixer to generate a single I analog drive signal and a single Q analog drive signal, and a single multi-dimensional optical modulator configured to modulate an optical carrier light using the single I analog drive signal and the single Q analog drive signal to produce a modulated optical signal for transmission. Alternatively, a transmitter comprises a complex mixer to generate two I analog drive signals and two Q analog drive signals, and a single multi-dimensional multiple-electrode optical modulator configured to modulate an optical carrier light using the analog drive signals to produce a modulated optical signal for transmission. In both transmitters, the optical carrier light is produced by a single laser, and frequency components of the first data signal are located in a different portion of a spectrum of the modulated optical signal than frequency components of the second data signal.Type: GrantFiled: September 30, 2016Date of Patent: January 2, 2018Assignee: Ciena CorporationInventors: James Harley, Roger Carroll, Shahab Oveis Gharan, Kim B.

Publication number: 20120241920Abstract: A method of cleaning polybenzoxazole (PBO) from a semiconductor wafer coated with PBO includes baking a PBO-coated semiconductor wafer, and then exposing the semiconductor wafer with ultraviolet light through a patterned mask to soften selected regions of PBO on the semiconductor wafer. PBO is then dissolved in an edge region of the semiconductor wafer with solvent. After dissolving PBO in the edge region, the semiconductor wafer is chemically developed to dissolve the elected softened regions of PBO on the semiconductor wafer and to dissolve PBO remaining in the edge region of the semiconductor wafer that was left behind after the step of dissolving the PBO in the edge region with the solvent.Type: ApplicationFiled: March 21, 2012Publication date: September 27, 2012Applicant: POLAR SEMICONDUCTOR, INC.Inventor: Roger Carroll
